GLOBE 0R CHIMNEY HOLDER FOR LAMP-BURNERS.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed February *7, 1910. Serial No. 542,468.

To all whom it may concern:

Be it known that I, CHARLES WV. CALD- WELL, a citizen of the UnitedStates, resid-v ing at Roanoke, in the county of Roanoke and State ofVirginia, have invented certain new and useful Improvements in Globe orChimney Holders for Lamp-Burners; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in globe or chimney holders forlamp burners.

The object of the invention is to provide a simple and efficientfastening mechanism for lamp burners whereby a chimney or globe will beheld thereon against casual removal and means whereby the fasteningmechanism may be released to permit the removal of the chimney whendesired.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure 1 is a side view partly in sectionof a lamp burner and chimney showing the application of the invention;Fig. 2 is a plan view of the burner; Fig. 3 is a detail section of theburner and chimney on the line 33 of Fig. 2.

Referring more particularly to the drawings, 1 denotes the burner towhich is secured an inner series of spring chimney catches 2 and 3. Thecatches 2 are provided on their lower ends with angular lugs, which areriveted to the upper side of the burner plate as shown. On the upperends of the catches 2 are formed outwardly projecting chimney engaginglugs 4, which are adapted to engage the shoulder 5 formed on the lowerend of the chimney 6, as shown.

The catch 3 has formed therein a spring loop 7 which is secured to thelower side of the burner plate, and the loop 7 depends below said platewhile the free end thereof forming the catch projects upwardly through asuitable slot formed in the plate and is provided on its upper end witha lug 8 adapted to engage the shoulder 5 of the chimney, as shown. Thefree arm of the catch 3 is provided on its outer side and preferablyimmediately below the burner plate with a push button or knob 9, wherebysaid catch arm may be forced inwardly to disengage the lug 8 thereonfrom the shoulder 5 of the chimney, thus permitting the latter to bereadily removed.

In addition to the inner series of catches 2 and 8, I also preferablyemploy a series of outer spring catches 10, which are also secured tothe burner plate and have out wardly bentor flaring upper ends, whichwill readily permit the flared lower end 11 of the chimney to be forcedinto engagement with the catches 10, when the spring catch 3 has beenforced back, after which, when the spring 3 is released, the chimneywill be securely held in place on the burner and cannot be casuallyknocked off or removed therefrom until the catch 3 is again pressedinwardly and the lug 8 thereon disengaged from the shoulder 5, ashereinbefore described.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claim.

Having thus described my invention,what I claim is In a lamp burner, achimney having a flared lower end and an inner annular shoulder, aninner series of spring catches secured to the burner and adapted toengage the inner side of said flaring end of the chimney, shoulderengaging lugs formed on the upper ends of said catches to engage theshoulder of the chimney, a spring formed in one of said catches, a knobarranged on said catch whereby the same is forced back against thepressure of said In testimony whereof I have hereunto set spring todisengage the lug thereon from my hand 1n presence of two subscriblngWitthe shoulder-0f the chnnney, and an outer nes'ses.
